Mar 12 2009 12:48PM EDT Ann Coulter's Book Sales Head South Though never exactly shy, Ann Coulter has been especially noisy in her self-promotion lately, inventing a beef with NBC News, arguing with Keith Olbermann over the meaning of a Cornell degree and taking her act on the road with Bill Maher as foil. Could it be because she's worried she's losing our attention? Coulter's latest book, Guilty: Liberal "Victims" and Their Assault on America, is something of a misfire by Coulterian standards. Of course, what constitutes a disappointment for Coulter would be a mega-hit for most authors; in its two months on sale, Guilty has sold 100,500 copies, according to Nielsen BookScan (a number that only reflects around 70 percent of actual sales). But with it moving steadily down the best-seller list, it looks certain that Guilty will fall far short of matching her earlier results. Her 2006 polemic, Godless: The Church of Liberalism, sold 279,100 copies in hardcover, according to BookScan; Treason: Liberal Treachery from the Cold War to the War on Terror, published in 2003, sold 396,600 hardcover copies, and 2002's Slander: Liberal Lies About the American Right, sold 333,100 copies, plus another 108,300 in paperback. (The two other books she published over that period, How to Talk to a Liberal (If You Must) and If Democrats Had Any Brains, They'd Be Republicans, are both collections rather than original works, so I left them out for the sake of apples-to-apples comparison.) No wonder Coulter's wishing out loud that the new administration had chosen to feud with her instead of Rush Limbaugh. Could it be that Barack Obama's America has a smaller appetite for Coulter's brand of take-no-prisoners, obey-no-logic conservatism?
